The type of language by friend or friendship
We all have a good friend, a friend rumbero, a smart friend, a sadistic friend another who knows all one who is a thief, one who consumes things weird but in the end they are our friends and we do not do what they do we learn from them good things as bad, what we should not do now think about
Well now what I mean is that each one of us manages his way of expressing himself depending on the communicative situation in which he is, depending on what he means, to whom he is addressing, in order to communicate in a way that the other person understands and can have a communication
So when we talk on the phone with a friend, we use everyday language, relaxed and full of confidence, but if we must talk to an adult, our language becomes more structured and we leave the security or trust aside.
In the same way, it is not the same to write a letter to a friend telling him about your vacations, than to write a letter of congratulations to the newspaper.
There are two ways to communicate: informal and formal.
The informal
This type of language is used when we talk with our parents and with people with whom we have great confidence. Example: among friends, acquaintances, relatives, classmates, among others. It is the language we use daily is characterized by being expressive and emotional, because we use it with people close to us, which allows us to use other elements such as nicknames, diminutives, etc.
He formal:
It is the type of language we use in situations that are more serious and formal with a doctor, boss or entity of respect, that we do not trust him and we do not know how to express ourselves and what his reaction will be.
